Interaction of Wilson loops in confining vacuum [PDF]

, 2002
Nonperturbative and perturbative interaction mechanisms of Wilson loops in gluodynamics are studied within the background field formalism. The first one operates when distance between minimal surfaces of the loops is small and may be important for sea ...

Numerical study of multiparticle scattering in λϕ 4 theory

Journal of High Energy Physics, 2018
We study numerically classical collisions of waves in λϕ 4 theory. These processes correspond to multiparticle scattering in the semiclassical regime.

Instanton effects in quark form factor and quark-quark scattering at high energy

, 2004
The nonperturbative effects in the high-energy processes involving strongly interacting particles are studied within the instanton liquid model of the QCD vacuum (ILM) by using the Wilson integral framework.

Unitary quantization of a scalar charged field and Schwinger effect

Journal of High Energy Physics, 2020
Quantum field theory in curved spacetimes suffers in general from an infinite ambiguity in the choice of Fock representation and associated vacuum. In cosmological backgrounds, the requirement of a unitary implementation of the field dynamics in the ...

Effects of nonperturbative improvement in quenched hadron spectroscopy [PDF]

Nuclear Physics B - Proceedings Supplements, 1999
We discuss a comparative analysis of unimproved and nonperturbatively improved quenched hadron spectroscopy, on a set of 104 gauge configurations, at beta=6.2. We also present here our results for meson decay constants, including the constants f_D and f_Ds in the charm-quark region.

Sequestering in String Compactifications

, 2010
We study the mediation of supersymmetry breaking in string compactifications whose moduli are stabilized by nonperturbative effects. We begin with a critical review of arguments for sequestering in supergravity and in string theory.

Nonperturbative effects in heavy quarkonia

, 1994
An effective hamiltonian for heavy quarkonia is derived from QCD by separating gluonic fields in background and quantum fields and neglecting anharmonic contributions. Mesonic states with nonperturbative gluonic components are constructed. These states are invariant under gauge changes of the background fields and form an orthogonal basis.
